Description

Technical Field

[0001] This utility model relates to the field of steering gear output shaft technology, and in particular to a steering gear output shaft. Background Technology

[0002] The function of a steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly by reducing speed and increasing torque) and then output them to the steering tie rod mechanism, thereby turning the car. Therefore, a steering gear is essentially a speed reduction transmission device. There are various types of steering gears, such as rack and pinion, recirculating ball, worm gear crank pin, and power steering.

[0003] The current announcement number CN207374476U discloses a steering gear output shaft, belonging to the field of automotive steering gear technology. It solves the problem of low strength in existing steering gear output shafts. This steering gear output shaft includes a body, one end of which is an input end with a connecting cavity, and the other end of which is an output end. A first gear is provided on the outer wall of the output end, and a buffer groove is provided in the middle of the first gear along the direction from the input end to the output end.

[0004] To address the issue of poor stability of the output shaft, existing technologies employ a one-piece structure for the steering gear output shaft, resulting in high strength. Furthermore, the diameters of the shoulder, reinforcing section, and main body differ, enhancing the overall strength of the output shaft. The annular groove effectively reduces stress in the main body, making it less prone to damage, thus improving the strength of the output shaft. However, this approach still suffers from the lack of quick-release mechanisms when connecting to other components, leading to more cumbersome maintenance in the later stages. Utility Model Content

[0005] In order to overcome the above-mentioned defects in the prior art, the present invention provides a steering gear output shaft.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a steering gear output shaft, including a steering assembly, wherein a direction assembly is provided on the top surface of the steering assembly.

[0007] A connecting rod is provided on the bottom side of the directional assembly. A high-strength L-shaped rod is slidably connected inside the connecting rod. A spring is fixedly connected to one side of the high-strength L-shaped rod. A universal coupling is slidably connected to the surface of the connecting rod. The interior of the universal coupling is slidably connected to one end of the high-strength L-shaped rod.

[0008] Furthermore, the universal coupling has a positioning groove inside and a positioning hole inside, and the inner side of the positioning hole is slidably connected to the surface of the connecting rod.

[0009] Furthermore, the universal coupling has a connecting shaft slidably connected inside, and a connecting block is fixedly connected to the surface of the connecting shaft slidably connected to the inside of the positioning groove.

[0010] Furthermore, a protruding rod is fixedly connected to one end of the first connecting shaft, and a second connecting shaft is slidably disposed on the surface of the protruding rod.

[0011] Furthermore, a limiting groove is provided inside the second connecting shaft, the inner side of the limiting groove is slidably connected to the surface of the protruding rod, a through hole is provided inside the limiting groove, and a sealing block is provided on the surface of the second connecting shaft.

[0013] Furthermore, the interior of the oil pipeline is hollow, and an oil drain hole is connected to the interior of the oil pipeline. One side of the oil drain hole is connected to the interior of the through hole.

[0014] The beneficial effects of this utility model are as follows: The design scheme, through the use of a high-strength L-shaped rod and spring, allows for the disassembly, inspection, and replacement of worn universal couplings after prolonged use, further enhancing ease of maintenance. The positioning groove and positioning hole facilitate the positioning of the connecting rod and connecting shaft. The positioning groove and connecting block reduce the stress on the positioning groove, further extending its service life.

[0019] Example 1 according to Figure 1-5 As shown, a steering gear output shaft includes a steering assembly 1, a direction assembly 2 is disposed on the top surface of the steering assembly 1, a connecting rod 3 is disposed on the bottom side of the direction assembly 2, a high-strength L-shaped rod 4 is slidably connected inside the connecting rod 3, a spring 5 is fixedly connected to one side of the high-strength L-shaped rod 4, a high-strength L-shaped rod 4 is slidably connected to the surface of the connecting rod 3, and a universal coupling 6 is slidably connected inside the universal coupling 6 to one end of the high-strength L-shaped rod 4.

[0020] In this embodiment, during use, the high-strength L-shaped rod 4 is pushed out of the interior of the universal coupling 6, while the spring 5 is compressed. At the same time, the connecting rod 3, connecting shaft 1 9, connecting shaft 2 12 and steering assembly 1 can be separated and disassembled. The universal coupling 6 can also be inspected. During installation, the positioning of the connecting block 10 and the positioning groove 7 facilitates the installation work. The positioning groove 7 reduces the stress on the high-strength L-shaped rod 4 and increases its service life.

[0021] Example 2 like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the universal coupling 6 has a positioning groove 7 inside, a positioning hole 8 inside, the inner side of the positioning hole 8 is slidably connected to the surface of the connecting rod 3, a connecting shaft 9 is slidably connected inside the universal coupling 6, a connecting block 10 is fixedly connected to the surface of the connecting shaft 9, the surface of the connecting block 10 is slidably connected to the inside of the positioning groove 7, a protruding rod 11 is fixedly connected to one end of the connecting shaft 9, and a connecting shaft 12 is slidably arranged on the surface of the protruding rod 11.

[0022] In this embodiment, during the use of the direction assembly 2, pulling the direction assembly 2 causes the protruding rod 11 on the bottom side of the connecting shaft 9 to slide inside the limiting groove 13 on the inner side of the connecting shaft 12, thereby adjusting the required height of the connecting shaft 12, and then adjusting it through the direction assembly 2.

[0023] Example 3 like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting groove 13 is provided inside the connecting shaft 2 12, the inner side of the limiting groove 13 is slidably connected to the surface of the protruding rod 11, a through hole 14 is provided inside the limiting groove 13, a sealing block 15 is provided on the surface of the connecting shaft 2 12, a thread 16 is provided on one side of the sealing block 15, an oil injection hole 17 is threadedly connected to the surface of the thread 16, the surface of the oil injection hole 17 is located inside the connecting shaft 2 12, an oil supply pipe 18 is sleeved at one end of the oil injection hole 17, the inside of the oil supply pipe 18 is hollow, an oil drain hole 19 is connected inside the oil supply pipe 18, and one side of the oil drain hole 19 is connected to the inside of the through hole 14.

[0024] In this embodiment, during long-term use, the rotating sealing block 15 slides out from the inside of the oil injection hole 17 through the thread 16, and then the lubricating oil is injected into the inside of the oil supply pipe 18 through the oil injection hole 17. Then, it is discharged into the inside of the limiting slide groove 13 through the oil drain hole 19 and the through hole 14, thereby realizing the contact between the lubricating oil and the protruding rod 11, reducing the wear of the protruding rod 11. At the same time, the sealing block 15 reduces the occurrence of oil leakage.

[0025] In use, this invention firstly involves pulling the steering assembly 2 during operation. This causes the protruding rod 11 on the bottom side of the connecting shaft 9 to slide within the limiting groove 13 inside the connecting shaft 12, thus adjusting the required height of the connecting shaft 12. The steering assembly 2 is then used to adjust the height. Simultaneously, during prolonged use, the rotating sealing block 15 slides out of the oil injection hole 17 via the thread 16, injecting lubricating oil into the oil supply pipe 18 through the oil injection hole 17. The lubricating oil then drains through the drain hole 19 and the through hole 14 into the limiting groove 13, thereby achieving lubrication between the lubricating oil and the protruding rod 11. The lifting rod 11 makes contact, reducing wear on the protruding rod 11. At the same time, the sealing block 15 reduces oil leakage. During long-term use, it pushes the high-strength L-shaped rod 4 out of the universal coupling 6, and drives the spring 5 to compress. This allows for the separation and disassembly of the connecting rod 3, connecting shaft 1 9, connecting shaft 2 12 and steering assembly 1. It also allows for the maintenance of the universal coupling 6. During installation, the positioning of the connecting block 10 and the positioning groove 7 facilitates installation. The positioning groove 7 also reduces the stress on the high-strength L-shaped rod 4, increasing its service life.
